Abstract

Basic devices required for analog microwave signal processing have been demonstrated using magnetostatic wave propagation in epitaxial yttrium iron garnet films. 100 nsec delay lines with bandwidths of 400 MHz, dispersive delay lines with differential delays of 200 nsec and bandwidths of 1 GHz and a programmable tapped delay line, all operating at S-band through X-band, are described. The operation of a new type of device, a signal-to-noise enhancer or power expander, is discussed which has the opposite characteristic to the more familiar microwave limiter. All these devices share the unique features of operation directly at microwave frequencies and frequency tunability via the strength of the magnetic bias field which is required for their operation.
